## Homework Statement

9.6 A table-tennis ball is thrown at a stationary bowling ball. The

table-tennis ball makes a one-dimensional elastic collision and bounces back

along the same line. Compared with the bowling ball after the collision, does

the table-tennis ball have (a) a larger magnitude of momentum and more

kinetic energy, (b) a smaller magnitude of momentum and more kinetic

energy, (c) a larger magnitude of momentum and less kinetic energy, (d) a

smaller magnitude of momentum and less kinetic energy, or (e) the same

magnitude of momentum and the same kinetic energy?
